there's this cranking sound in our focus tdci when you depress the clutch pedal midway.. we'll we brought it to casa and they told us that we need to replace the clutch assembly. then after the clutch got changed the problem still remains. now they told us to replace the flywheel.. and will cost us 38k for the whole assembly.. now my question is.. can the flywheel be repaired? and where can we take it to be repaired?
